Another familiar face will return to terrorize the cast of Teen Wolf in season 5.

'Teen Wolf' Season 5: Stiles' Mom Slated For 'Heart-Wrenching' Flashback, Jeff Davis Explains

Numerous heroes and villains have filtered through Beacon Hills over the last four seasons, and one of them will return under the guise of this year's big bads.

"This character has been on the show before, but we won't say who!" Tyler Posey (Scott) teased, according to E! Online. "He's making a comeback."

'Teen Wolf' Season 5 Spoilers: Parrish's Big Reveal Won't Happen This Summer? Jeff Davis Explains

Well, thanks to Posey's little hint, we can certainly knock anyone of the female persuasion off our suspect list, including Kate Argent (Jill Wagner), the Darach (Haley Webb), Alison (Crystal Reed), Mrs. Argent (Eaddy Mays), Cora Hale (Adelaide Kane), and Braeden (Megan Tandy).

No thanks to showrunner Jeff Davis' propensity for reviving the deceased, the list of potential returnees is quite lengthy. Although it doesn't help to narrow the suspect pool, Holland Roden (Lydia) dished out a little spoiler about the mysterious character's unsettling looks.

"There's one particular prosthetic that they use this season that is on somebody's face and it's not really that monstrous; it's just more eerie," Roden told E! Online.

So, who do you think this nefarious mystery man is? Was it someone who battled Scott's pack in the past, or will it be an old ally gone rouge? Sound off in the comments below!
